I don't think it's weird that it matches. Lots of moms buy matching things.
As for little stuff that you need, don't forget mittens for the baby, so he doesn't scratch his face. you might need diaper rash ointment, shampoo, one of those booger sucker things, baby tylenol, a bottle brush can be helpful. Basics like bibs, pacifiers, swaddle blankets...
I want all my stuff to match i dont find it wierd.. Shower tubby, eventually a high chair for eating, baby detergents, comb/temperature/nail clipper kit etc.
